Introduction (1) FLOODSTANDWhy FLOODSTAND ?
• missing data for validation of time-domain numerical tools for assessment of passenger ship survivabilityand
• a standard for a comprehensive measure of damaged ship stabilityaddressing the flooding risk- reflecting the stochastic nature of damaged ship stability in waves- based on first-principles modeling - reflecting foundering as a process (loss of flotation/stability)- considering risk-based decision making

Numerical modeling and criteria for leaking and collapsing structures => Work completed
Responsible: MEC; Other Participants: CTO, NAPA, STX
- Focus on failure mechanisms for doors and structural components
- Numerical simulations; explicit FEM code
- Flow rate vs. water pressure
- Specific data obtained also on
-- the leakage pressure, i.e. when the structure
looses watertight integrity and-- the collapse pressure gets it to collapse.
- Computations will be validated with experiments
=> criteria for leakage and collapse of doors etc.
